PH Balancing

(1/2) > >>

brian_tr:
Every time I change my water it takes two bottles of ph down and 1 1/2 bottles of calcium to bring my Alkalinity and ph and hardness in. I usually do it by added a little bit every day for around three weeks. I was wondering since I know how much it takes if I can just add one whole bottle at one time of ph down and one bottle of calcium to speed things up?

tubin:
have you tried adding a bottle of "perfect ph"?  i think robarb makes it.  you add a bottle to new water and it is supposed to buffer the water to the correct ph and prevent swings for the life of the water.

i didn't add my bottle the first fill up so i can't tell you how well it works, but i have seen dips in ph.

maybe someone else can chime in?

Hi Brian
Just do it a little at a time ....
You are after all adding ACID to the water and if this suddenly goes too high it is very corrosive both to your pump and heater !
a little and often .... well thats what my wife says anyway !

Shut_Down_Stranger:
It depends on the form of calcuim

Calcium = Water Hardness

pH Balancer = Bicarbonate/Carbonate = Alkalinity.

Generally you should add the alkalinity (pH Balancer) to the water before the adding the calcium (hardness). This way the water is buffered and can adjust to the calcium which may be acidic depending on the form.

Thanks.  It seems like it always takes me about a month to get ph down.  I am going to try and add about a 1/4 bottle at a time and see how that works.  Will slow down when I start to see a drop in ph.  It takes over a bottle before it gets down enough to where I can even get a reading.
